AUTOMATIC FIREARM.

Specification of Letters Patent.

Patented Nov. 24, 1914.

Application filed April 4, 1914. Serial No. 829,489.

To all whom it may concern:

Be it knownlthat I, JOHN HOWARD CARL, a citizen of the United States, residing at Gilroy, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Automatic Firearms, of which the following is a speci fication.

, This invention relates to firearms and has special reference to a demountable recoil loading firearni. v

The principal object of the present invention is to provide a novel arrangement of means for locking the barrel on the stock or frame of such a firearm wherein the bolt retracting spring shall also serve to hold the locking pin for the barrel in locking position.

A second object of the invention is to provide an improved detent for the barrel in such a firearm.

A third object of the invention is to provide improved means for holding the locking pin from rotation so that it may assist in forming the detent for the barrel.

A fourth object of theinvention is to provide means on such locking pin for adjusting the tension of the bolt retracting spring.

IVith the above and other objects in view the invention consists essentially in the features and combinations hereinafter claimed.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and: Figure 1 is a side elevation, partly in section, of a firearm embodying this invention. Fig. 2 is a plan view of the forestock, the barrel being re moved. Fig. 3 is a section on the line 33 Fig. 4 is a section on the line of Fig. 1. Fig. 5 is a detail perspective view of a certain adjusting stop or clip used in this invention.

It is to be understood that only those parts of this firearm that have to do with the objects to be accomplished, as hereinafter set forth, will be described in the present application specifically; the remaining parts being described in general.

In the present embodiment, as illustrated in the drawings, there is disclosed a' firearm having a stock 10, forestock 11, barrel 12, hammer 13, trigger 14 and sliding bolt 15; these numerals indicating the respective parts in general. The forestock 11 is provided with the .usual groove 16 wherein slides the bolt 15 which has its forward end formed with side portions 17 and an end portion 18, said side and end portions being provided with lips 19 which project inwardly as shown in Figs. 1 and 2.

Located in the groove 16 between the sides 17 of the bolt is a lug 20 which is provided with a vertical recess 21 having an enlarged mouth 22. Opening forwardly from this recess into the groove 16 is an opening 2. At the forward end of the forestock there is provided an opening 24 al-ining with the opening 23. In like man- .ner, the portion 18 of the bolt is provided with an opening 25 which, when the parts are assembled, alines with the openings 23 and 24. Slidable through these openings is a pin 26 which is provided with a head 27 having parallel side edges fitting between ribs 28 on the front end of the forestock.

The rear end of this pin is provided with aplura-lity of pairs of oppositely disposed notches 29 to receive the legs of a U-shaped clip 30 so that a coiled spring 31 may be placed around the pin with one end bearing against the clip and the other end hearing against the inner side of the portion 18 of the bolt thereby both holding the pin in position and constantly urging said bolt forward. Moreover, by shifting the clip from one pair of notches to another the tension of the spring may be varied. On the side walls of the forestock there are provided certain upstanding ribs 32 which are arranged to enter grooves 33 in the under side of the barrel 12 and said barrel is also provided with a shouldered lug 34, adapted to fit the recess 21, and having a locking notch 35 therein which, when the parts are assembled receives the beveled end 36 of the pin 26 so that the barrel is locked on the forestock. Now the rear end' of the barrel is securely held by said lug 34 while the forward end is held by the ribs 32 and grooves 33 assisted by the concave upper surface 37 of the pin head 27 into which the circular portion 38 of the barrel seats.

To take down the firearm the pin is withdrawn sufliciently to release the lug 34 whereupon the barrel is lifted off. The clip 30 is then removed and the pin entirely withdrawn. Finally the spring is taken out and the bolt will then be left loose so that are put back in the reverse order.

' upwardly extendin There has thus been provided a simple and efficient device of the kind described and of the character specified.

Having thus described the invention, what is claimed as new, is

1. In a take-down'firearm, a frame including a forestock, a bolt reeiprocable in said frame and having a slotted front end, a recessed lug on said forestock in the groove of the frame, a locking pin extending through the front ends of said forestock and bolt and entering said lug, a removable clip on said pin adjacent the lug, and a spring surrounding said pin and bearing against said clip and the front end of the bolt, said spring serving to hold the bolt closed and the pin in locked position; in combination with a barrel having a lug on its under side arranged to fit the recess in the first mentioned lug and provided with a recess for engagement by the end of the lockingpin.
